Across the Corn Belt, warm, mostly dry weather is nearly ideal for late-developing corn and soybeans, except for locally heavy showers in the upper Midwest. While not as warm as yesterday, Wednesday’s high temperatures will average more than 10 degrees above normal across northern-most portions of the region.
On the Plains, a continuation of warm, mostly dry weather is promoting fieldwork and summer crop maturation. The dry weather is favorable across the northern Plains, where last week’s downpours impeded small grain harvesting. Conversely, increasingly dry conditions on the southern Plains have depleted soil moisture for winter grain planting.
In the South, hot, dry weather is accelerating summer crop maturation and harvesting but depleting topsoil moisture and stressing pastures. However, Tropical Depression Imelda is generating locally heavy showers in southeastern Texas, while Hurricane Humberto continues to move northeastward away from the southern Atlantic Coast.
In the West, cool air lingers over the Pacific Coast states, accompanied by locally heavy showers in the northern Rockies and Northwest. Meanwhile, dry weather has returned to the Four Corners Region, heightening drought concerns after a poor Southwestern monsoon, which typically provides parts of the region half of their annual precipitation.
Tropical Depression Imelda is moving slowly north across eastern Texas, producing locally heavy rain and flash flooding. Conversely, high pressure anchored over the Atlantic Coast will maintain mostly sunny skies across the eastern third of the nation while deflecting Hurricane Humberto out to sea.
Initially cool conditions in the East Coast states will be replaced by increasing warmth, as above-normal temperatures (up to 10 degrees above normal) currently over the nation’s midsection shift east. Meanwhile, a cold front will bring showers and thunderstorms to the north-central U.S. before dissipating, while a second, stronger cold front currently pushing into the Northwest will produce rain and mountain snow from the Pacific Northwest into the northern Rockies.
This second front will also generate locally heavy showers across the Midwest over the weekend, while the southern tail of the front potentially brings much-needed rain to the southern Plains. Out West, cooler-than-normal conditions will prevail from the Rockies to the Pacific Coast, with more showers expected in the Northwest.
Looking ahead, the 6- to 10-day outlook calls for above-normal temperatures nationwide, save for a pocket of near- to below-normal temperatures in the Intermountain West. Near- to above-normal precipitation is also expected across much of the nation, with drier-than-normal conditions confined to Deep South Texas and from the Southeast to the southern New England Coast.
